Continuous Measurement of Aging Response in Aluminum Alloys By Eddy Current Methods
Abstract
The objective of this research was to investigate further the use of a sensor system to continuously monitor the aging response of heat treatable aluminum alloys. This concept of continuous monitoring is referred to as Intelligent Processing. The bridge consists of eddy current coils incorporated in an impedance bridge circuit, with modifications following earlier work by Esarey. The system continuously monitors a material property, resistivity, indicative of the aging process. The results of such continuous measurements, combined with mechanical test data, will allow one to gain active control of the aging process and hence the material properties of aluminum alloys. The ultimate results would be higher reliability of engineering structures. The increased precision in control of heat treatment processes would allow more narrow performance and greater service life of engineering structures.
